Lift and drag experiments on D-type surface geometry
Experimental and theoretical developments in the study of turbulence have revealed several surface roughness geometries that reduce viscous drag. The interaction between structures in turbulent flow and patterns of structures of similar size on the surface can reduce global viscous drag. Experiments...

| Summary: | Experimental and theoretical developments in the study of turbulence have revealed several surface roughness geometries that reduce viscous drag. The interaction between structures in turbulent flow and patterns of structures of similar size on the surface can reduce global viscous drag. Experiments are shown that begin to map the combinations of water speed, groove size and spacing that accomplish this. NRC publication: Yes |
